Memory in Old Age may be Improved with Blueberries, Green Tea

by Thilaka Ravi on July 22, 2010 at 8:12 AM Diet & Nutrition News

University of South Florida researchers found that a combination of nutrients called NT-020 made from blueberries, green tea, and amino acids, such as carnosine, successfully promoted adult neural stem cell proliferation in aged rats and boosted their memory performance.

The researchers were studying natural therapeutic approaches to promoting the health of neurons in the aging brain.

They tested two groups of aged laboratory rats; one group received NT-020 and another, the control group, did not.

In the NT-020 group, the process by which neurons are generated-called neurogenesis- increased.

The NT-020 formula was patented by USF and licensed to Natura Therapeutics, Inc.

"Aging has been linked to oxidative stress, and we have previously shown that natural compounds made from blueberries, green tea, and amino acids, such as carnosine, are high in antioxidants and have anti-inflammatory and anti-oxidative activity. The combination of these nutrients, called NT-020, creates a synergistic effect that promotes the proliferation of stem cells in the aged animals," said Dr. Sandra Acosta, the study's lead author.

The NT-020 group demonstrated increased adult neural stem cell proliferation in the two main stem cell niches in the brains and improvement in learning and memory.
